 SkyWalking APM 8.0.0 is release. Go to [downloads](/downloads) page to find release tars.
 
-- v3 protocol is added and implemented
-- New Dashboard UI and new Query Protocol are provided
-- Prometheus fetcher is supported. Once you have Prometheus SDK instrumented app, the metrics could be read by SkyWalking.
-- Register mechanism has been removed due to buckets effect on performance and memory cost.

+* Data Model could be added in the runtime, don't depend on the bootstrap sequence anymore.
+* Reduce the memory cost, due to no inventory caches.
+* No buffer files in tracing and service mesh cases.
+* New ReadWriteSafe cache implementation. Simplify codes.
+* Provide default way for metrics query, even the metrics doesn't exist.

+
+#### Document
+* Add v8 upgrade document.
+* Make the coverage accurate including UT and e2e tests.
+* Add miss doc about collecting parameters in the profiled traces.
+
+#### CVE
